RAD Studio is the ultimate IDE with features both C++ and Delphi developers love to design, code, debug and test for cross-platform platform with native performance.

Supported Platforms: Windows, iOS, macOS, Linux, and Android (some platforms Delphi only)

Major Delphi Code Insight Redesign: The largest and best improvement to Delphi’s code tooling in many years, RAD Studio 10.4 provides Code Insight using a Delphi implementation of the Language Server Protocol (LSP).

• LSP is a technique for calculating results for code completion, navigation, or similar in a separate process. This means that the IDE will never block while completing and Code Insight will provide accurate results.
• You can also use code completion while debugging.
• 10.4 provides a much enhanced developer productivity experience when working with large projects with millions of lines of code.
• Accurate Error Insight results (red squiggles) and errors shown in the structure view.

Delphi – Custom Managed Records:

• A key language addition to the Delphi language, the Delphi record type now supports custom initialization, finalization, and copy operations.
• Developers now have the ability to customize how records get created, copied, and destroyed, by writing the code to be executed at the various steps.
• This adds additional power to records in Delphi, a construct used to achieve better efficiency compared to classes.

Unified Memory Management for Delphi and C++:

• Delphi memory management is now unified across all supported platforms – mobile, desktop, and server – using the classic implementation of object memory management. Compared to Automatic Reference Counting (ARC), this offers better compatibility with existing code and simpler coding for components, libraries, and end-user applications. The ARC model remains for string management and interface type references for all platforms.
• For C++, this change means that the creation and deletion of Delphi-style classes in C++ follow normal memory management just like any heap-allocated C++ class, significantly reducing complexity.

New C++ Builder Features:

• Expanded C++ libraries support : Ported numerous popular C++ libraries to C++Builder, providing optimized support for use within C++Builder. This includes libraries such as ZeroMQ, SDL2, SOCI, libSIMDpp, and Nematode, as well as others already supported such as Eigen, available for download through the GetIt Package Manager.
• Win 64-Debugging and Linker for C++ : A new debugger for Windows 64-bit for C++. Based on LLDB, this debugger introduces significant stability improvements when debugging 64-bit applications, as well as a key new feature assisting evaluating and inspecting types like C++ and Delphi strings plus STL collections.
• Toolchain performance and quality improvements: A large number of STL improvements from Dinkumware, Several key RTL methods, Several improvements to CMake support.

VCL Styles for High DPI:

• The VCL Styles architecture has been extended to support High DPI and 4K monitors. All UI controls on the VCL form are now automatically scaled for the proper resolution of the monitor the form is displayed on. The style API has been fully revised to support high DPI styles.
• Updated a large number of our built-in and premium VCL styles to provide support for the new High-DPI style mode, letting you design visually stunning applications for any monitor.
• VCL Per Control Styling -VCL developers can now use multiple VCL styles in different forms within a single application or even different visual controls that are on the same form. This also enables you to use third-party unstyled controls within a styled VCL application.

New VCL Components: 

• Edge Browser Control A new VCL web browser component, TEdgeBrowser, that uses Microsoft’s new Edge WebView2 based on Chromium. TWebBrowser component has been extended, allowing browser controls in an existing application to use either the existing Internet Explorer or Edge browsers for display, depending which browser is available on the system.
• TTitleBarPanel and Custom Title Bars : The new TTitleBarPanel control and TForm.CustomTitleBar property allow you to customize a VCL form’s native Windows title bar. You can place VCL controls on the Windows title bar, control the default painting of elements such as the window icon and caption, add new custom system buttons near the Minimize, Maximise and Close buttons, or even custom paint the title bar entirely. This enables you to build modern enhanced title bars, similar to Office, Explorer, Google Chrome, or other applications.
• Image Component with Multi-Resolution Support: There is a new TVirtualImage component that supports multiple resolutions and DPI scaling, allowing you to gain high-quality image scaling and display by replacing the classic TImage component.

Key FireMonkey Platform Enhancements:

• Metal Driver GPU Support for macOS and iOS: On the macOS platform (Delphi), you can now build applications against the Metal API.
• In addition to supporting the latest iOS SDK, It also address Apple’s new launch screen storyboard requirement through built-in IDE support.
• This release includes a new FMX implementation for the styled TMemo component on the Windows platform, offering better support for IME and additional enhancements.
• Enterprise and Architect Edition customers can take advantage of FMXLinux integration for building Linux GUI applications.
• The TWebBrowser control for iOS is now implemented using the WKWebView API
• The macOS implementation of Media Player control now used AVFoundation
• Developers using the FireMonkey framework can target the latest versions of the supported operating systems.

Run-Time Library Enhancements:

• Enhanced Parallel Programming Library Support: Made numerous performance and stability enhancements to PPL library.
• FireDAC database access library and also updated the drivers for FireBird, PostgreSQL, and SQLite.
• Expanded our HTTP and REST Client libraries with additional HTTPS features and also expanded our support for Amazon AWS services.
• LiveBindings Performance and Features Enhancements.

IDE Enhancements:

• GetIt Package Manager Enhancements This includes displaying release dates for each package with the ability to sort them by release date; new filtering options for installed packages, exclusive content available for update subscription customers, packages for which updates are available;
• Unified Installer for Online & Offline installations This provides a single installer that supports both online (internet connected) installations and offline installations (via an ISO). Now both online and offline installations allow you to select an initial set of RAD Studio features to install, such as support for specific combinations of programming languages and target platforms, language support, or help resources, and add or remove them at any time.
• The code editor has several productivity improvements, including new settings such as file codepage and font size on the editor status bar.
• The IDE and key dialogs use the new TCustomTitleBar control to implement search and settings on the title bar, enabling native look and feel and Windows DWM behavior.
